/**
 * A builder for creating {@link JsonObject} models from scratch. This
 * interface initializes an empty JSON object model and provides methods to add
 * name/value pairs to the object model and to return the resulting object.
 * The methods in this class can be chained to add multiple name/value pairs
 * to the object.
 *
 * 

The class {@link javax.json.Json} contains methods to create the builder * object. The example code below shows how to build an empty {@code JsonObject} * instance. *

 * 
 * JsonObject object = Json.createObjectBuilder().build();
 * 
 * 
* *

The class {@link JsonBuilderFactory} also contains methods to create * {@code JsonObjectBuilder} instances. A factory instance can be used to create * multiple builder instances with the same configuration. This the preferred * way to create multiple instances. * * * The example code below shows how to build a {@code JsonObject} model that * represents the following JSON object: * *

 * 
 * {
 *     "firstName": "John", "lastName": "Smith", "age": 25,
 *     "address" : {
 *         "streetAddress": "21 2nd Street",
 *         "city": "New York",
 *         "state": "NY",
 *         "postalCode": "10021"
 *     },
 *     "phoneNumber": [
 *         { "type": "home", "number": "212 555-1234" },
 *         { "type": "fax", "number": "646 555-4567" }
 *     ]
 * }
 * 
 * 
* *

The code to create the object shown above is the following: * *

 * 
 * JsonBuilderFactory factory = Json.createBuilderFactory(config);
 * JsonObject value = factory.createObjectBuilder()
 *     .add("firstName", "John")
 *     .add("lastName", "Smith")
 *     .add("age", 25)
 *     .add("address", factory.createObjectBuilder()
 *         .add("streetAddress", "21 2nd Street")
 *         .add("city", "New York")
 *         .add("state", "NY")
 *         .add("postalCode", "10021"))
 *     .add("phoneNumber", factory.createArrayBuilder()
 *         .add(factory.createObjectBuilder()
 *             .add("type", "home")
 *             .add("number", "212 555-1234"))
 *         .add(factory.createObjectBuilder()
 *             .add("type", "fax")
 *             .add("number", "646 555-4567")))
 *     .build();
 * 
 * 
* *
